Hayes' "yes" tweet has since been deleted.

MGMT quickly took to Twitter to clarify that the album art had been licensed from Maruo. The reason this whole controversy even happened, however, is because Hayes has been accused of copying from Maruo in the past.

This was only one in a number of tweets from different users alleging that Hayes was copying work from various Japanese artists and repurposing it as her own.

Kago told BuzzFeed News that he is regularly reached out to by other people to obtain permission to use his art, but has never been contacted by Hayes. "I looked up Jeanette Hayes on my e-mail, Twitter DM, and Facebook Messenger, but none of them matched; so I never had a conversation with her," he said. "In regards to the incident, I haven’t heard anything from her as of now."

Hayes has since deleted this Instagram post.

In one post, it seems that Hayes may have simply screenshotted another artist's work.

BuzzFeed News reached out to Brodsky about the incident. Brodsky said that she thought Hayes had started to use the image "at a time when my account was small and no one really knew about my work."

"I actually found her work via an article about up-and-coming young artists, looked her up, and was surprised and upset to find my work represented as hers," she said. "I believe I wrote her to ask her about it but she never responded, and never took down the image or gave me credit for it."

The above post also remains on Hayes' Instagram without credit.

And throughout Twitter, there are numerous examples of Hayes lifting from other artists' work without credit.

The recent string of posts about Hayes aren't the first time she has been accused of profiting from others' work without credit or acknowledgement. Animal New York published a piece in 2014 about Hayes painting another artists' meme, and then selling it at auction.

At the time, the original artist, Mattie Hillock, told Animal, "Honestly, it’s an appropriation of an appropriation. I made the work as a joke and now seeing it actually just easily put up like that… Kind of hurts. But it shouldn’t hurt. It’s like, good job. *Wince.*”

While Hayes has many critics, she remains supported by galleries. One Twitter user shared a screenshot of New York's Castor Gallery defending Hayes' work.
